REAL NUMBERS :
a number which is either rational or irrational is called a real number.
RATIONAL NUMBERS :
A number that can be expressed as p/q , where p,q are Integers and q≠0 is called a rational number.
IRRATIONAL NUMBERS :
A number that cannot be expressed as p/q , where p,q are Integers and q≠0 is called a irrational number.

Hi,
0.142857 is a rational number .
Since it is a terminating decimal.
0.142857
= 142857/1000000
= 142857/( 10^6 )
= 142857/( 2^6 × 5^6 )
= p/q
denominator q is the form 2^n × 5^m,
( n = 6 and m = 6 )
I hope this helps you.
